[0018] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0019] like Figures 1 to 7 As shown, according to an embodiment of this disclosure, a radome repair fixture 100 is provided, including: a base 110; a mounting bracket 120 disposed on the base 110, wherein a receiving space 101 is defined between the base 110 and the mounting bracket 120, the receiving space 101 being used to receive the radome 200 to be repaired; wherein the base 110 and / or the mounting bracket 120 are provided with an exhaust port 102, the exhaust port 102 being used to supply protective gas to the receiving space 101.

[0020] The radome repair fixture 100 provided in this embodiment includes a base 110 and a mounting bracket 120. The mounting bracket 120 is disposed on the base 110 and defines an accommodating space 101 between the mounting bracket 110 and the base 110. The accommodating space 101 can be used to accommodate the radome 200 to be repaired, so that the radome 200 to be repaired can be stably placed during the repair process. One of the base 110 and the mounting bracket 120 is provided with an exhaust port 102 for supplying protective gas into the accommodating space 101. Thus, during the repair of the radome 200 to be repaired, the radome repair fixture 100 can use the exhaust port 102 to continuously blow protective gas into the aforementioned accommodating space 101, so that the humidity of the environment where the radome 200 to be repaired is located is relatively low. This can reduce the risk of excessive surface humidity of the radome 200 to be repaired during the bonding repair process, provide a guarantee for the success rate of bonding repair, and thus help improve the repair efficiency of the radome and reduce the repair cost of the radome.

[0021] It should be noted that the radome repair fixture 100 provided in this embodiment can be applied to, but is not limited to, the thermal bonding repair of radomes for civil aircraft. For example... Figure 6 and Figure 7 As shown, in practical applications, the radome 200 to be repaired can be placed in the aforementioned accommodating space 101. At least one of the mounting bracket 120 and the base 110 can be directly or indirectly connected to the radome 200 to provide structural support for the radome 200 and ensure the positional stability of the radome 200 during the repair process. The air inlet of the aforementioned exhaust port 102 can be connected to a gas source, which is used to output the aforementioned protective gas. The aforementioned protective gas can be, but is not limited to, an inert gas or nitrogen. The air outlet of the exhaust port 102 is arranged facing the accommodating space 101, so that the exhaust port 102 can blow the protective gas output from the aforementioned gas source into the accommodating space 101.

[0022] It is understandable that the diameter, number, and exhaust flow rate of the exhaust port 102 can be set according to actual needs, as long as the exhaust port 102 can continuously supply protective gas to the accommodating space 101 during the output process of the aforementioned gas source, without making too many restrictions here.

[0023] It is understood that in practical applications, the aforementioned accommodating space 101 can be an open space, that is, at least one side of the accommodating space 101 is open, thereby facilitating the entry and exit of repair tools and / or maintenance personnel, and improving the convenience of repair operations. For example, the aforementioned mounting bracket 120 and the aforementioned base 110 are connected to form a generally L-shaped frame structure, and the inner space of the aforementioned L-shaped frame structure is configured as the aforementioned accommodating space 101, thereby allowing multiple sides of the aforementioned accommodating space 101 to be open, facilitating the approach and departure of repair tools and / or maintenance personnel from different directions to the radar dome 200 to be repaired, thus facilitating repair operations at different damage locations.

[0024] like Figures 1 to 7 As shown, in some examples, the base 110 includes: a support frame 111, the support frame 111 having a first gas channel and an exhaust port 102, the first gas channel being used to connect the gas source and the exhaust port 102; wherein, the mounting bracket 120 is disposed on the support frame 111.

[0025] In this technical solution, the base 110 may include the aforementioned support frame 111, which may have the aforementioned first gas channel and the aforementioned exhaust port 102. Based on the aforementioned configuration, on the one hand, the support frame 111 can serve as the main structure of the base 110, providing structural support for the mounting frame 120 and the radome 200 to be repaired during use, ensuring the structural reliability and stability of the radome repair fixture 100; on the other hand, the support frame 111 can also utilize the first gas channel to provide a communication path between the exhaust port 102 and the aforementioned gas source, facilitating the connection of the exhaust port 102 with protective gas and avoiding the need for a separate gas connection fitting, which helps reduce the difficulty of pipeline layout and improves the structural compactness of the radome repair fixture 100; furthermore, with the exhaust port 102 located on the base 110, the height of the exhaust port 102 can be relatively low, allowing the protective gas output from the exhaust port 102 to diffuse more evenly into the accommodating space 101, which helps improve the humidity control effect of the radome repair fixture 100 on the accommodating space 101.

[0026] It is understandable that the aforementioned first gas channel can be directly or indirectly connected to a gas source.

[0027] For example, the aforementioned support frame 111 can be a frame structure composed of multiple first steel pipes connected together, wherein the internal space of at least one first steel pipe is configured as the aforementioned first gas channel, and correspondingly, the exhaust port 102 can be opened on the pipe wall of the first steel pipe having the first gas channel. Based on this, on the one hand, the support frame 111 is easy to manufacture using profiles, which can reduce the manufacturing cost of the support frame; on the other hand, while ensuring the structural strength of the support frame 111, the weight of the support frame 111 can be reduced, thereby improving the lightweight level of the radome repair fixture 100, which can facilitate the relocation of the radome repair fixture 100 during use.

[0028] It is understood that the aforementioned first steel pipe can be a square steel pipe or a round steel pipe. When the aforementioned first steel pipe is a square steel pipe, it is easier to open the aforementioned vent hole 102 and reduce the difficulty of drilling holes on the load-bearing frame 111.

[0029] like Figures 1 to 3 , Figure 5 and Figure 6 As shown, in some examples, the radome repair fixture 100 also includes: a shut-off valve 130 disposed on a mounting bracket 120, the mounting bracket 120 having a second gas passage, the second gas passage connecting the exhaust end of the shut-off valve 130 and the first gas passage, the inlet end of the shut-off valve 130 being connected to a gas source, and the shut-off valve 130 being used to connect or disconnect the gas source from the second gas passage.

[0030] In this technical solution, the radome repair fixture 100 may further include the aforementioned shut-off valve 130, and the aforementioned mounting bracket 120 may have the aforementioned second gas passage. Based on the aforementioned configuration, the radome repair fixture 100 can use the shut-off valve 130 to control the output of the exhaust port 102. Furthermore, by placing the shut-off valve 130 on the mounting bracket 120, the position of the shut-off valve 130 relative to the base 110 can be correspondingly higher, thereby facilitating the operation and observation of the shut-off valve 130 by maintenance personnel and improving the ease of use of the radome repair fixture 100.

[0031] It is understood that the aforementioned shut-off valve 130 can be a manual shut-off valve 130 or an electric shut-off valve 130; the shut-off valve 130 and the aforementioned gas source can be directly connected or indirectly connected.

[0032] like Figures 1 to 3 , Figures 5 to 7 As shown, in some examples, the base 110 also includes a walking mechanism 112, which is disposed on the support frame 111.

[0033] In this technical solution, the base 110 may also include the aforementioned walking mechanism 112. Based on the aforementioned configuration, the base 110 can move and cooperate with the ground or maintenance platform through the aforementioned walking mechanism 112, thereby facilitating the transfer of the radome maintenance tooling in practical applications and further improving the ease of use of the radome repair tooling 100.

[0034] For example, the aforementioned walking mechanism 112 may include a plurality of casters, which are spaced apart at the bottom of the support frame 111.

[0035] like Figures 1 to 3 , Figures 5 to 7 As shown, in some examples, the mounting bracket 120 includes: a support column 121 disposed on the base 110; a crossbeam 122 disposed on the support column 121; and a connecting bracket 123 disposed on the crossbeam 122, the connecting bracket 123 being rotatably connected to the radome 200 to be repaired.

[0036] In this technical solution, the mounting frame 120 may include the aforementioned support column 121, crossbeam 122, and connecting frame 123. Based on the aforementioned configuration, the mounting frame 120 can rotatably connect to the radome 200 to be repaired via the connecting frame 123. This allows the radome 200 to have rotational freedom during use, facilitating attitude adjustment of the radome during repair. This, in turn, facilitates repair of different damaged parts of the radome, improving the convenience of repair work. Furthermore, the mounting frame 120 can support the connecting frame 123 using the support column 121 and crossbeam 122, allowing the connecting frame 123 to be positioned higher relative to the base 110. This expands the distribution range of the accommodating space 101 and provides a more spacious area for the rotational adjustment of the radome 200 to be repaired.

[0037] It is understood that the radome typically has a hinge 201. In practical applications, the hinge 201 can be rotatably connected to the aircraft fuselage, thereby facilitating the opening and closing of the radar compartment. Correspondingly, the connecting frame 123 can be rotatably connected to the hinge 201. The number of connecting frames 123 can be set in conjunction with the number of hinges 201. In practical applications, the connecting frames 123 can be connected to the hinges 201 in a one-to-one correspondence.

[0038] It is understood that there can be multiple support columns 121, and multiple support columns 121 are connected between the crossbeam 122 and the base 110, thereby improving the installation stability of the crossbeam 122 and the connecting frame 123.

[0039] For example, the aforementioned support column 121 and crossbeam 122 can be made of a second steel pipe, wherein the internal space of at least one second steel pipe is configured as the aforementioned second gas channel. Based on this, on the one hand, the support column 121 and crossbeam 122 are easy to manufacture using profiles, which can reduce the manufacturing cost of the support frame; on the other hand, while ensuring the structural strength of the mounting frame 120, the weight of the mounting frame 120 can be reduced, thereby improving the lightweight level of the radome repair fixture 100 and facilitating the relocation of the radome repair fixture 100 during use.

[0040] It is understood that the aforementioned second steel pipe can be a square steel pipe or a round steel pipe.

[0041] like Figure 3 and Figure 5 As shown, in some examples, the support column 121 is a telescopic structure so that the position and height of the connecting frame 123 relative to the base 110 are adjustable.

[0042] In this technical solution, the support column 121 can be a telescopic structure, allowing the position and height of the connecting frame 123 relative to the base 110 to be adjustable. Based on this, the radome repair fixture 100 can have high structural flexibility, facilitating the adjustment of the placement height of the radome 200 to be repaired. Furthermore, combined with the rotational connection between the connecting frame 123 and the radome 200 to be repaired, it can further improve the flexibility of the radome's position and orientation adjustment during maintenance, thereby facilitating the repair of different damaged parts of the radome and improving the convenience of repair operations.

[0043] For example, the support column 121 may include: a sleeve, one end of which is disposed on the base 110; an inner tube, which passes through the sleeve and is adapted to extend or retract into the sleeve through the other end of the sleeve; a first mating hole is provided on the wall of the sleeve, and at least one second mating hole is provided on the wall of the inner tube; the axial direction of the first mating hole is parallel to the axial direction of the second mating hole; and a limiting member, which is detachably disposed in the first and second mating holes, and restricts the relative movement of the inner tube and the sleeve when the limiting member is disposed in the first and second mating holes; wherein the inner tube has a first working position and a second working position; when the inner tube is in the first working position, the inner tube is inside the sleeve, and the crossbeam 122 abuts against the end of the sleeve away from the base 110; when the inner tube is in the second working position, the first mating hole and at least one second mating hole are coaxially arranged.

[0044] like Figures 1 to 7 As shown, in some examples, the radome repair fixture 100 further includes a support frame 140 having a mounting end and a support end, the mounting end being detachably disposed on the base 110, and the support end being used to support the radome 200 to be repaired.

[0045] In this technical solution, the radome repair fixture 100 may further include the aforementioned support frame 140. Based on the aforementioned configuration, the support frame 140 can be supported between the radome 200 to be repaired and the base 110, thereby cooperating with the mounting frame 120 to constrain the position and orientation of the radome 200 to be repaired, which is beneficial to improving the position and orientation stability of the radome 200 to be repaired.

[0046] like Figure 4 As shown, in some examples, there are multiple exhaust ports 102, which are arranged at intervals; and / or The exhaust port 102 is in the shape of a round hole or a strip-shaped hole.

[0047] In this technical solution, there can be multiple exhaust ports 102, and the multiple exhaust ports 102 are arranged at intervals, which can increase the protective gas output flow rate of the radome repair fixture 100, expand the protective gas blowing range, and help improve the dehumidification performance of the radome repair fixture 100.

[0048] In this technical solution, the exhaust port 102 can be circular, thereby reducing the complexity of the exhaust port 102's design and saving on the cost of creating the exhaust port 102. Alternatively, the exhaust port 102 can be strip-shaped, allowing the radome repair fixture 100 to blow a protective gas curtain through the exhaust port 102, which helps to expand the protective gas blowing range and improve the dehumidification performance of the radome repair fixture 100.

[0049] In some examples, the cross-sectional area of ​​the exhaust port 102 increases along the direction from the air inlet end to the air outlet end of the exhaust port 102.

[0050] In this technical solution, the cross-sectional area of ​​the exhaust port 102 can be increased along the direction from the air inlet end to the air outlet end of the exhaust port 102. Based on this, the diffusion efficiency of the protective gas output by the exhaust port 102 can be improved, which is conducive to expanding the distribution range of the protective gas, reducing the ambient humidity around the radar dome 200 to be repaired, and improving the dehumidification performance of the radar dome repair fixture 100.

[0051] In some examples, the base 110 and / or mounting bracket 120 are made of structural steel.

[0052] In this technical solution, at least one of the base 110 and the mounting bracket 120 can be made of structural steel, which can improve the structural stability and reliability of the radome repair fixture 100, help the radome repair fixture 100 to stably support the radome 200 to be repaired, and extend the service life of the radome repair fixture 100.

[0053] For example, the aforementioned structural steel may be, but is not limited to, Q235 carbon structural steel.
